<p>From the movie, My Cousin Vinny:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>Mona Lisa Vito: So what&#39;s your problem?
Vinny Gambini: My problem is, I wanted to win my first case
without any help from anybody.
Mona Lisa: Well, I guess that plan&#39;s moot.
Vinny : Yeah.
Mona Lisa: You know, this could be a sign of things to come.
You win all your cases, but with somebody else&#39;s help, right?
You win case after case, and then afterwards you have to go up
to somebody and you have to say, &quot;thank you.&quot;
[pause]
Oh my God, what a fucking nightmare!
</pre></div>

<p>Leo owes much of its visual design to MORE, possibly the most elegant computer program ever written. <br />
More inspired Leo’s cloned nodes.</p>
<p>Leo’s very important people:</p>
<ul class="simple">
<li><p>David Brock wrote TSyntaxMemo, used in early versions of Leo.</p></li>
<li><p>Terry Brown wrote important plugins, including Leo’s user-modifiable panes.</p></li>
<li><p>e inspired &#64;button nodes, a brilliant idea.</p></li>
<li><p>The late Bob Fitzwater kept me focused on design. <br />
Oh, how I wish he could see today’s Leo.</p></li>
<li><p>Jonathan M. Gilligan showed how to put the Leo icon in Leo’s windows.</p></li>
<li><p>The Jupyter development team taught me how to support pygments colorizing.</p></li>
<li><p>Brian Harry contributed numerous plugins, including a prototype for Leo’s minibuffer, and wrote jyLeo: Leo in Jython.</p></li>
<li><p>Almar Klein wrote pyzo, yoton and flexx, the basis of LeoWapp (–gui=browser).</p></li>
<li><p>Donald Knuth invented the CWEB language and literate programming.</p></li>
<li><p>The late Bernhard Mulder invented the &#64;shadow algorithm, the foundation of &#64;clean. <br />
Bernhard also inspired Leo’s generators and position class.</p></li>
<li><p>Joe Orr created LeoVue and XSLT stylesheets for Leo.</p></li>
<li><p>John K. Ousterhout created tcl/Tk, used in early versions of Leo.</p></li>
<li><p>Виталије Милошевић, (Vitalije Milosevic) made vital code-level contributions.</p></li>
<li><p>Tsuchi Noko created transparent icons.</p></li>
<li><p>Neal Norwitz wrote PyChecker.</p></li>
<li><p>Félix Malboeuf wrote leoInteg, LeoJs, leoserver.py and leoclient.py.</p></li>
<li><p>Marc-Antoine Parent urged me to use XML for Leo’s file format and helped improve it.</p></li>
<li><p>Paul Paterson created the plugin architecture, helped with spell checking and contributed many plugins.</p></li>
<li><p>François Pinard wrote pymacs, the foundation of Leo’s emacs bridge.</p></li>
<li><p>Norman Ramsey created noweb and gave permission to quote from the noweb web documentation.</p></li>
<li><p>Edward K. Ream is Leo’s project leader and chief programmer.</p></li>
<li><p>Rich Ries has contributed a huge number of suggestions.</p></li>
<li><p>Guido van Rossum created Python.</p></li>
<li><p>Steven P. Schaefer pointed out security problems.</p></li>
<li><p>Gil Shwartz helped with unicode support.</p></li>
<li><p>Phil Straus has been a great friend and constant support.</p></li>
<li><p>Kent Tenney contributed key insights about vnodes and lobbied to make Leo easier to use.</p></li>
<li><p>Ville M. Vainio contributed to the one-node world, the IPython bridge and several plugins.</p></li>
<li><p>Paul S. Wilson greatly improved Leo’s Wikipedia entry.</p></li>
<li><p>Dave Winer created MORE, the foundation of Leo’s visual design.</p></li>
<li><p>Dan Winkler helped support Leo on the Mac.</p></li>
</ul>
<p>Special thanks to my family. My brother, David Speed Ream, tested Leo and made many useful suggestions. Rebecca, James and Linda make it all worthwhile. During a conversation with Rebecca I realized that MORE could be used as a prototype for Leo. That was a crucial first step.</p>
<p>The following people reported bugs, answered questions, and made suggestions for improving Leo:</p>
